  • The Present compound was diluted with dimethyl sulfoxide to obtain a diluted solution containing 500 ppm of the compound, 1 µL of the diluted solution was dispensed into a titer plate (96 well), and thereto was then dispensed 150 µL of a potato dextrose broth medium (PDB medium) to which spores of Pythium ultimum were inoculated in advance. This plate was cultured at 23°C for 5 days, thereby allowing Pythium ultimum to undergo proliferation, and the absorbance at 550 nm of each well of the titer plate was then measured to obtain a value as a degree of growth of Pythium ultimum. As a result, the degree of growth in the well treated with the Present compound was 50% or less relative to the degree of growth in the untreated well.
